1
Q
Semiconductor
A
Material that is neither a good conductor or a good insulator
2
Q
What is meant by doping
A
adding impurities to a semi conductor to change the conductivity of the material
3

4
Q
What is added to make majority charge carrier Holes
A
Boron
5
Q
Difference between intrinsic and extrinsic conduction
A
Intrinsic has equal number of hole sand electrons and extrinsic doesn’t
6
Q
What is a depletion layer
A
high resistant region with no charge carriers
7
Q
Explain how a depletion layer is formed
A
p-type is connected to a n-type and diffusion occurs and create a biased p-n junction
